Stephen King's The Dark Tower series is going to be adapted for the small and big screen.
Universal has acquired the rights to turn the seven novels, short stories and comic books into three films and an NBC series.
Ron Howard will direct the first film and the first season of the TV show.
"I've been waiting for the right team to bring the characters and stories in these books to film and TV viewers around the world," the author said in a statement.
Ron and Universal's "deep interest and passion for the The Dark Tower series ... will translate into an intriguing series of films and TV shows that respect the origins and the characters in The Dark Tower that fans have come to love," he added.
More than 30 million copies of The Dark Tower have been sold in 40 countries. After the series was completed, a prequel of comic books based on one of the characters was also published.
Director Ron said: "By using both the scope and scale of theatrical filmmaking and the intimacy of television we hope to more comprehensively do justice to the characters, themes and amazing sequences King has given us in The Dark Tower novels.
"It might be the challenge of a lifetime but clearly a thrilling one to take on and explore."
